At the tidings some of his weight of woe appeared to be lifted from the head of the millionaire. “Good!” he said, “good! Gentlemen, you will lunch with me, I hope.” “Thank you,” said M. Formery. “There is nothing else for us to do, at any rate at present, and in the house. I am not quite satisfied about Mademoiselle Kritchnoff—at least Guerchard is not. I propose to question her again—about those earlier thefts.” “I’m sure there’s nothing in that,” said the Duke quickly. “No, no; I don’t think there is,” said M. Formery. “But still one never knows from what quarter light may come in an affair like this. Accident often gives us our best clues.” “It seems rather a shame to frighten her—she’s such a child,” said the Duke. “Oh, I shall be gentle, your Grace—as gentle as possible, that is. But I look to get more from the examination of Victoire. She was on the scene. She has actually seen the rogues at work; but till she recovers there is nothing more to be done, except to wait the discoveries of the detectives who are working outside; and they will report here. So in the meantime we shall be charmed to lunch with you, M. Gournay-Martin.” They went downstairs to the dining-room and found an elaborate and luxurious lunch, worthy of the hospitality of a millionaire, awaiting them. The skill of the cook seemed to have been quite unaffected by the losses of his master. M. Formery, an ardent lover of good things, enjoyed himself immensely. He was in the highest spirits. Germaine, a little upset by the night-journey, was rather querulous. Her father was plunged in a gloom which lifted for but a brief space at the appearance of a fresh delicacy. Guerchard ate and drank seriously, answering the questions of the Duke in a somewhat absent-minded fashion. The Duke himself seemed to have lost his usual flow of good spirits, and at times his brow was knitted in an anxious frown. His questions to Guerchard showed a far less keen interest in the affair. To him the lunch seemed very long and very tedious; but at last it came to an end. M. Gournay-Martin seemed to have been much cheered by the wine he had drunk. He was almost hopeful. M. Formery, who had not by any means trifled with the champagne, was raised to the very height of sanguine certainty. Their coffee and liqueurs were served in the smoking-room. Guerchard lighted a cigar, refused a liqueur, drank his coffee quickly, and slipped out of the room. The Duke followed him, and in the hall said: “I will continue to watch you unravel the threads of this mystery, if I may, M. Guerchard.” Good Republican as Guerchard was, he could not help feeling flattered by the interest of a Duke; and the excellent lunch he had eaten disposed him to feel the honour even more deeply. “I shall be charmed,” he said. “To tell the truth, I find the company of your Grace really quite stimulating.” “It must be because I find it all so extremely interesting,” said the Duke.
